Catfish fossils are mainly represented by disarticulated material, most of which is dorsal and pectoral spines. Morphological data on dorsal and fin spines are described. These materials, collected from two sites of the Adamantina and Marilia formations,

Freeze Brand Retention in Channel Catfish and Channel Catfish × Blue Catfish Hybrids
North American Journal of Fisheries Management, 2017Abstract We evaluated freeze brands on Channel Catfish Ictalurus punctatus and hybrid catfish (female Channel Catfish × male Blue Catfish I. furcatus) to determine suitability of the technique for identification of year-class on ictalurid catfishes.

Journal of Neurophysiology, 1979
1. We define absolute sensitivity as (voltage/illuminance) and incremental sensitivity as the peak-to-peak amplitude of the first-order (Wiener) kernels. 2. Incremental sensitivity of the horizontal cells is the local slopes of the Michaelis-Menten equation and that of more proximal neurons is the Fechner slope.

Annual Review of Animal Biosciences, 2018
This article summarizes the biology and culture of ictalurid catfish, an important commercial, aquaculture, and sport fish family in the United States. The history of the propagation as well as spawning of common catfish species in this family is reviewed, with special emphasis on channel catfish and its hybridization with blue catfish. The importance

Southern Medical Journal, 1995
We reviewed a series of 83 catfish sting cases from inland hospitals (Belzoni and Indianola) and a coastal hospital (Pascagoula) to identify the type and severity of injury, as well as the type of treatment and its effectiveness. Oral cephalosporin was adequate in treating early infections.

The Journal of Hand Surgery, 1991
Catfish skin toxin and the venom from their dorsal and pectoral spines may cause a menacing sting. Although these stings are often innocuous, severe tissue necrosis may occur. The hand is the most common site of catfish stings. Two cases of catfish stings of the hand are presented.

Abstract Information on the infectivity of Ichthyophthirius multifiliis (Ich), a severe fish parasite that causes high mortality, is limited for blue catfish ( Ictalurus furcatus ) and catfish hybrids (CB hybrid) resulting from female channel catfish ( Ictalurus punctatus ) × male blue catfish crosses.

Abstract This study was conducted to gain a better understanding of the effect of exposure to the myxozoan Henneguya ictaluri (the agent of proliferative gill disease [PGD]) on host physiology by measuring the variation in selected blood characteristics in three differently affected host taxa (channel catfish Ictalurus punctatus, blue ...
